Pour point depressant made by hydrovisbreaking and deasphalting a shale oil

Patent ·
OSTI ID:7081061
;
A process is described for producing a pour point depressant for shale oil which comprises mixing a deasphalting solvent, under deasphalting conditions, for instance, at a temperature of up to about 250/sup 0/F at a pressure up to about 500 psig, with a shale oil which has had its viscosity and pour point lowered as a result of contact with hydrogen under hydrovisbreaking conditions. The mixture of shale oil and deasphalting solvent is then separated into deasphalted shale oil and a heavier portion containing the pour point depressant for shale oil. Compositions comprised of shale oil and the pour depressant are also disclosed.
